>> Complete coverage of i686 user-mode opcodes also matters to me. > Why? Because I have my own compilers. Also, even when clients use gcc, I could then recommend valgrind without having to add the caveat, "you might see some unhandled instruction bytes, which means that progress stops for some time while either valgrind adjusts its code or you adjust yours." And it's hard when the offending opcode is in glibc, such as 'fxtract' for *logb(). -- |
